Electrical questions, answered by experts

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

Yes, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

If you’re interested in exploring other avenues to completely upgrade your electrical panel, it’s also possible to add a sub-panel, which is a smaller panel that connects to what you currently have in place. This way, you can add additional circuits without having to swap out your main panel.

A 3-prong, 15-amp, 120-volt outlet is standard in the U.S. These have two vertical slots and a U-shaped grounding hole, which suits most home electronics, from televisions to microwaves. Three-pronged outlets are safer than 2-pronged ones, as the third wire, known as the grounding wire, helps prevent shocks and electrical fires.
